Whenthe cover 3 ismoved from; the=subcover since the projecting point ofthe lug 9 has now entered the ring latch 6, where it will remain untilmanually released from engagement with the said latch 6 as V is clearlyshown in Figs. 1 and As a means for releasing the said latch 6 fromitsengage nientwith thelug 9,. the pull chain 10 has been provided. Thischa n 10"is secured to the latch means of the eye 11 located at thelower end of latch 6; W hen the chain 10 is pulled, the latch 6 is drawnor swungbach-wardtoward the cover 3, which operation releases the lug 9from engagement with the latch 6 thereby unlocking the said cover 3 andpermit of its being opened. 1

. The jfoldable extension side pieces 12 and 13 secured to the cover. 3preferably by means of the hinges 14 and 15 respectively, areprovidedforthe purposesof forming, in combination withthe cover 3, a means fordirecting and guiding material into the chute;;,a meansfor safeguardingthe chute; a means for protecting the public against entering the chute;and finally as a means of supportto the cover 3 when it is opened tooccupy a vertical position. H When the chute is to be placed in aninoperative condition as by closing the cover 3, the foldable extensionside pieces 12 and 18 may be'swung inwardly against the cover 3. s Theopenings 16 and 17' in the side pieces 12 and 13 respectively, are solocated as to register one above the other, and both to pass over thefastening 18. This fastening 18 may be any well known form of swivelfastening device secured to the cover 3.

When the foldable extension side pieces 12 and 13 are folded against thecover 3, the chain 10 may first'be placed so as to occupy a positionbetween thesaid folded extension side pieces and the under side of thecover 3, as shown in Figs. 1 and 3. Should the chain 12 be disposed ofin this manner it must be done so that the said chain may bemoved orpulled backward, in which position the chain 10 tends to be maintainedby friction and the force of gravity, or either of them. The chain 10may then be continued down into the hopper 1 and thence into and whollythrough the chute passage 19 leading from the chute hopper 1 to thedischarging point of the chute, from which point the chain may continueto any convenient location, thereby permitting the operation of thelatch 6 from the terminus of the chute, or at some other distantlocation. hen the latch 6 has been released the cover 3 may be opened bymeans of the ring 20, to a vertical position, in which position thecover 3 may be held by means of the unfolded extension side pieces 12and 13 as shown in Fig. 2. Stops 21 and 22 have been provided on theside pieces 12 and 13 re- 6 preferably by 1.
